Survival and conjugal transfer between Bacillus thuringiensis strains in aquatic environment

Field and laboratory studies were conducted to assess the survival of cells and spores and plasmid transfer between Bacillus thuringienis strains in aquatic environment. Results indicated that cells and spores of B. thuringiensis can survive for 10 days in water, without altering their number. The s...

Description
Summary:Field and laboratory studies were conducted to assess the survival of cells and spores and plasmid transfer between Bacillus thuringienis strains in aquatic environment. Results indicated that cells and spores of B. thuringiensis can survive for 10 days in water, without altering their number. The sporulation process began after 12-15 hours of inoculation of water. B. thuringiensis was able to transfer conjugative plasmids in the aquatic environment. O presente trabalho é um estudo sobre a sobrevivência e a conjugação de linhagens de Bacillus thuringiensis em água. Os experimentos conduzidos no laboratório mostram que as células e os esporos de B. thuringiensis podem persistir pelo menos 10 dias na água. A esporulação inicia-se 12-15 horas após a inoculação. O processo de conjugação foi demonstrado em diferentes ambientes aquáticos, tanto em condições de laboratório quanto no meio ambiente.
